One of the most iconic guitar tones in alternative rock. Johnny Marr's tone on How Soon Is Now? is built on a Rickenbacker 330 through a Fender Twin Reverb with extreme tremolo effect. The tremolo is the defining feature: a pulsating, rhythmic wobble that gives the song its hypnotic, driving feel. Marr used four separate amp channels processed with tremolo at different speeds, then blended them to create a massive, swirling stereo effect. The result is a guitar tone that sounds like it is breathing.
